It would be important to get your associations to religion, religious groups, and family groups. How is your family like a religious group or not like it? Does your family practice religion? And how does your attitude contrast with the "religion" in this dream?

The stalker could be a part of your personality that is persistently trying to assert itself, yet something about that part of you is uncomfortable to you. Hence, the stalker following you around with unwelcome attention. Say more about your association to the stalker. What do you think he is thinking or feeling?

Your family members and fellow church members are behaving in a self-sacrificing way. That term can describe any way that a person gives up some of their own needs in the service of something else. There is no support or familial love in this dream family, and no one values their own life enough to preserve it.

It seems like a kind of infection that has taken over the group. So the dream is saying that there is something in your life which takes you over (perhaps the same thing affects your real life family) and causes you to lose perspective on your own needs. It causes you to lose touch with love and care for other people and for yourself. Does that bring anything to mind?
